Efforts have been made to group the various types of key that are most commonly used by the public at large. A suitable die casting method is used taking into account such limitations as the sizes of the keys, their serviceability, rate of production, as they affect the method of producing the unit price of the key blanks and the selection of materials. The new design and construction is an improvement over the existing one in use, which utilizes only one space in the mould for the production of the blank key. If the technique is put into practice, it will save the country's foreign exchange earnings and could also discourage the importation of blank keys from abroad.

Key words: Die-Casting, Mould, Design, Production, Key Blanks
